springmvc 项目单元测试

对于web项目如果希望通过url来进行单元测试，但是启动服务器和建立http client 来进行测试非常麻烦，并且依赖网络环境。这样我们可以通过引入MockMvc进行测试。

 

一、引入jar包　

        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-test</artifactId>
            <version>${spring.version}</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>com.jayway.jsonpath</groupId>
            <artifactId>json-path-assert</artifactId>
            <version>0.8.1</version>
        </dependency>        

 

二、测试代码

　　1、dao层和service层

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:applicationContext.xml"})
@TransactionConfiguration(transactionManager="txManager",defaultRollback=true)
@Transactional//应用事务，这样测试就不会在数据库中留下痕迹

public class BaseJunit4Test { 
　　@Test 
　　public void test(){ 
　　} 
}

 

public class LoginServiceTest extends BaseJunit4Test{
    
    @Autowired
    private LoginService loginService;

    @Test
    public void testLogin() {
        String account = "kyle";
        String password = "123456";
        String result = loginService.Login(account, password);
        assertEquals("登陆成功",result);
    }

}

 

public class LoginMapperTest extends BaseJunit4Test{
    
    @Autowired
    private LoginMapper loginMapper;

    @Test
    public void testGetUserPwdByAccount() {
        String account = "kyle";
        String pwd = loginMapper.getUserPwdByAccount(account);
        assertEquals("123456",pwd);
    }

}

 

　　2、web层测试

@RunWith(SpringJUnit4ClassRunner.class)//使用Spring Test组件进行单元测试
@ContextConfiguration(locations={"classpath:applicationContext.xml",//加载配置文件 "classpath:spring-mvc.xml"
})
@WebAppConfiguration
@TransactionConfiguration(transactionManager="txManager",defaultRollback=true)
@Transactional//应用事务，这样测试就不会在数据库中留下痕迹

public class BaseWebJunit4Test { protected MockMvc mockMvc; protected MockHttpSession mockHttpSession; @Autowired protected WebApplicationContext context; @Before public void initMockMvc() throws Exception { mockMvc = MockMvcBuilders.webAppContextSetup(context).build(); this.mockHttpSession = new MockHttpSession(); mockMvc.perform(MockMvcRequestBuilders.post("/login") .contentType(MediaType.APPLICATION_FORM_URLENCODED) .param("account", "kyle") .param("password", "123456") .session(mockHttpSession)) .andExpect(status().isOk()) .andExpect(content().string("登陆成功")) .andDo(print()) .andReturn().getResponse().getContentAsString(); } @Test public void test(){ } }

 

public class LoginControllerTest extends BaseWebJunit4Test{
    
    @Test
    public void testLogin() throws Exception {
        mockMvc.perform(MockMvcRequestBuilders.post("/login")
                    .contentType(MediaType.APPLICATION_FORM_URLENCODED) 
                    .param("account", "kyle")
                    .param("password", "123456")
                    .session(mockHttpSession))
                    .andExpect(status().isOk())
                    .andExpect(content().string("登陆成功"))
                    .andDo(print())
                    .andReturn().getResponse().getContentAsString();
    }
    
    @Test
    public void testGetUserInfo() throws Exception {
        mockMvc.perform(MockMvcRequestBuilders.post("/getUserInfo")
                    .contentType(MediaType.APPLICATION_JSON) 
                    .content("{\"account\":\"kyle\"}")
                    .session(mockHttpSession))
                    .andExpect(status().isOk())
                    .andExpect(jsonPath("$.password", is("123456")))
                    .andDo(print())
                    .andReturn().getResponse().getContentAsString();
        
    }

}
